Virtual instruments in electrical engineering

Virtual instruments can be used to simulate the action of measurement systems on software generated signals or they can run as computer coupled measuring equipment which can acquire data from the approached process, followed by analysis, interpretation and result display. The main purpose of LabVIEW graphical programming environment is to offer users the possibility to rapidly develop their own virtual instrumentation systems in accordance to their specific needs. By using mostly didactic interactive-participating and metacognitive strategies the student is placed in the centre of the instructive-educational process and is stimulated to participate effectively in the development of theoretical and applicative activities revaluating his spirit of initiative independence and creative potential.
